Minutes of the Inter-Domain Policy Routing Working Group (IDPR)


Summary

The IDPR Working Group met for a single session at the November IETF in
Houston.  The time was divided among a discussion of IDPR Version 2, an
excellent video on ``Routing by Preference'' from Yuko Murayama, and
IDPR Working Group business.

IDPR Version 2 provides policy-based multicast and multipath routing as
well as policy-based resource allocation.  To support the features of
Version 2, the IDPR protocols required only minor changes.
Specifically, the path control protocol, route generation procedure, and
routing information distribution protocol underwent minor modifications.
An Internet-Draft describing IDPR Version 2 will be available early in
1994.

The IDPR Version 1 software for route generation and path control
required major redesign for Version 2.  Ram Ramanathan and Regina
Rosales Hain described the software simplifications and flexibility
resulting from their redesigns.  Version 2 software will begin rigorous
testing in December.  To obtain a copy of the Version 1 or Version 2
software, please send e-mail to idpr-wg-request@bbn.com.

Routing by preference, as presented by Yuko Murayama of the WIDE project
in Japan, involves selecting routes that factor in both source and
destination preferences, such as which domains are unfavorable and the
type of route preferred through unfavorable domains.  The example of
``preference'' presented in the video was to take the shortest (minimum
delay) paths through unfavorable domains.  Interested parties are
encouraged to read the paper on routing by preference submitted to the
list by Yuko, and to write to her about suggestions for solutions to the
problem presented.  The IDPR discussion list should be included in
responses as the problem is of interest to the group.

There are two updated Internet-Drafts available concerning IDPR: one is
the MIB and the other is the DNS support for IDPR. Comments should be
submitted to the authors and to the IDPR discussion list.  The IDPR
Working Group Chair would like the MIB submitted as a Proposed Standard.

The IDPR Working Group will suspend for the time being.  We have
accomplished all that we can without an independent Version 1
implementation.  We plan to resume when there exists an independent
implementation of IDPR Version 1 or when the Version 2 Internet-Draft
becomes available, whichever occurs first.

In the meantime, the working group mailing list will remain open to
handle the unfinished business of the updated Internet-Drafts and to
discuss issues relevant to IDPR.
